Detailed Description:
-
High-Density I/O Combination: Integrates 16 digital inputs (24V DC) and 16 digital outputs (24V DC, transistor, sourcing/PNP) within one module, saving installation space and cost.
-
Digital Input Characteristics: All 16 inputs are designed to acquire standard 24 V DC sensor signals and support both sink (NPN) and source (PNP) wiring.
-
Digital Output Characteristics: All 16 outputs are transistor outputs (sourcing/PNP) with a rated current of 0.5 A. Transistors offer fast switching speeds, making them suitable for controlling loads like indicator lights, relay coils, small solenoid valves, and especially for applications requiring high-speed pulse outputs.
-
Diagnostic Functions: The output channels feature short-circuit protection and overload diagnosis, and can detect loss of load voltage (L+). Fault information is reported to the CPU.
-
Electrical Isolation: Both input and output channels are optically isolated from the backplane bus to enhance noise immunity.
-
Compact and Flexible: The module has a width of 45 mm and mounts directly to the right side of an S7-1200 CPU or other modules via an integrated U-type connector. All parameters are configured via TIA Portal software.
-
Application Scenarios: Suitable for machinery and equipment requiring numerous connections for pushbuttons, sensors (inputs) and control of actuators like valves, contactors, indicator lights (outputs), such as packaging machines, assembly lines, material handling systems, etc.
